Specification of Letters Patent.

Application led May 25, 1907.A Serial No. 375`,720. 'l

To'aZZ whom 'it may concern: BeV it known that I, EDWIN .CourLAND SHAW,a citizen of the United States, residing at, Akron, in the county .ofSummit and State Of hio,have invented certain new and usefulImprovements in Vehicle Wheeltion.

' detachable rim Rims, of which the following is a specicaf.

' ulhis rim is made detachable and is provided with means for carrying atire. Rims of this character are especially adapted for use withpneumatic tires and one ofmy objects isto provide adetach'able rim towhich the tire may be applied while detached and inflated,

'a unitary fstructurethus being provided in A which thetire and rim aresecurely held together and can be transported and applied to a wheelwhenever desired, A consider-- able saving of .time in changing a tirecan thus be made, as the tire to be put on is already 'infiated and theapplication of the to the wheel is a much simpler operation than thesomewhat diiiicult process of applying a large and heavy pneumatic tireto the fixed rim of the old fashioned type.

This case presents a. modification of theA structures shown in myapplications Serial ANumbers 375,715 and 375,719, led May 25,

1907,'and of, my Patent lNo. 971,318, dated September 27,1910, in-whichapplications 40 able rim, the valve stem,

Referringto the 'drawings b reference numerals: 1 is -the fellysto whicis fixedly.

invention relates to vehicle ,wheel rims'of that class in vwhich onepart of the;

illustrated are claimed broadly.

attached in any suitable manner the fixed run or felly band 2. Thelatter' referabl'y has a substantially flat or cyli'n rical surface uponwhich seats the split detachablev rim 3. As a matter of practicalexpedienc thecentral part of the surface of the Vfe y band is preferablydepressed slightly below thel side portions thereof, which latter thusthe split .detachable rim seats. Such a depression 1s not essential, butfacilitates the ratentedrenn, 1914.

.form the actual bearing surface upon which manufacture of the fellyband, as it is not n vnecessary with this structure to turn the fellyband true throughout its 'entire width. A more even bearing of the.,detachable rim upon the cylindrical side portions of the felly Aband isassured andithc danger of the zot detachable rim rustingtolefiell-ysband soM tightly as to interfere with its ready removal Y iseliminated'. The split detachable rim-3 is provided with a downwardlyprojecting iange 4a adaptedto bear against one edge of the fixedl rim '2`to prevent lateral displacement of the detachable rim in one drectionand isalso provided with upstanding flanges 4 at its edges. Endless tireretaining 'flanges 5 adapted to engage the-'detachable rim are preventedfrom 'outward displacement'by these upstanding flanges4.

suitablel form depending upon the-typep' tire which it is desired touse. I have shown them asfshaped to engage a clencher tire 6.

Thel split detachable rim 3 may be contract-v ed -by lapping its endspast eachothprwsgo that the tire and tire retaining 'fianges-f5' may bepassed over its upstanding anges as is necessary in applying or'removingthe tire. Means are provided for locking the ends of the detachable rimtogether and ad- .5, justing ttheir relative' position;r In' 'this jmodification these 'means consist of a. pair of elongated lugs eachadapted to ybe rigldly. secured to, or integrally formed upon, one endofthe detachable rim. Said lugs project beyond said end and are providedwith ya pair Iof oppositely inclined screw threaded sockets 8. Betweenthe sockets,..each ofthe.

depression 9 in its upper fac`e. 'Screw andl()a are adapted to bescrew/edf'insockets. These. screws are provided rounded or otherwisesuitablyl formed ends 11 and with heads- 12 adaptedto b.

T e n rini provided related to enter the w .carrwinff c. V is aV '"ptedto sieinsertcd between each pair of screws and may be provided with.recesses to be engaged by the rounded ends of the said screws. .It -willthus be seen that by screwing up one screw of the pair and unsere ingthe other, it will be possible to move one end of the detachable rimwith relation to the other end and to hold it in desired. positi r lAAie operation of the devic is as follows: Supposing it to be desired toput tire upon the detachable rim which has been. removed from the fixedrim, the screws l() and 1Ga are drawn apart sufficiently to release thelugs le, whereupon the end of the rim carrying the lugs 7 is depressedso that the ends of the rim can be lapped past each other, thus reducingthe diameter of the 'rim sufficiently to permit one of the retainingflanges 5 to be removed. The tire can now be readily slipped over thedetachable rim and the flange 5 put back when the rim will be expandedand 'the lugs lll set back into place. rIhe screws l are nouT screwed upand the screws l0 Withdrawn thus forcing the rim 3 in close and rigidengagement with the endless tire retaining flanges 5. The tire can nouvbe inflated and the detachable rim and tire will be firmly fixedtogether. As the detachable rim is now cxpanded to its fullest diameter7it will readily slip over the fixed rim 2 until tlie.lla1igc 1l bearsagainst the edge of the fixed rim, it being of course understood thatthe valve stem. is first slipped through its proper opening in the lixedrim and felly. tcrews l0 are new Withdrawn slightly and screws l0screwed in, thus drawing the ends of the detachable rim together untilthe detachable rim. tightly clamps thefixed rim. fl`he ends of thedetachable rim need only be drawn together slightly to do this so thatthere will heno appreciable space between the detachable rim and theinside of the tire retaining flanges 5; To remove the detachable rim andtire the process is reversed. The frictionai engagement of thedetachable rim with the fixed rim is sullicient to hold it in place, butI may use additional locking means in the shape of set screws l5 carriedin tubular nuts 16 passing through the felly and fixed rim. These nutsi6 are provided at their upper ends with annular flanges 17 adapted toseat in recesses in the fixed rino. The ends of the set screws engageshallow recesses 18 in the inner surfaces of the detachable rim.AAnynumbcr of these set screws may be used though I prefer to use three,spaced equal distances apart. Gams 4or other equivalents for the screws.may he used.

It will be obvious that when the split rosa@ lues i l l l r r l creasedbythe action of the endless Hanger,-

5, which, as 'will be seens have inclined outer faces bearing againstthe inclined faces of the flanges fl. The pressure of the air in thetire forces the endless rings or flanges laterally, causine theirinclined faces to Wedge against the lianges 4. lVhen the screws 1G havebeen sufficiently withdrawn, therefore.) it Will be seen that the splitrim is lirinly clamped upon the felly by the pressure -of the air in thetire7 this clamping elle-ct being amply suiiicient to hold the rim uponthe felly during operation. The screws l0 are for the purpose ofexpanding the rim when it is to he removed. and also act to hold the rimin expanded position until it is placed upon the felly. After the rimhas been contracted upon thefelly by the air pressure, these screwsv l()have completed their function and may, if desired, be :entirelyWithdrawn from their sockets. I prefera however, to leave them partlyscrewed into their sockets, as they do notk interfere With the properoperation of the rim and they are thereby maintained in position :torimmediate operation when the rim is to be removed. l'Vhile the pressureot' the air in the tire is sullicient to contract the rim upon the fellyand hold it'irmly in place7 as a matter of precaution I use the screws10a, which forni auxiliary fastening means, these screws being forcedinto en-v gagement with the lugs 14 after the split rim has beencontracted upon it firmly by the air pressure. These screws do notinterfere with the contraction of the rim under the influence of the airpressure in the tire, but. prevent accidental expansion of the rim suchas might occur, for instance7` if the tire should become unintentionallydeflated.

While I have shown and' described one specific form of my invention asan illustration7 it is not to be understood that I intend to limitmyself to the precise embodiment 0r exact details set fort-h, but thatmodifications may be freely made so long'as the essential and operativecombination of elements is retained. For example, it VWill be understoodthat the means described and illustrated for expanding and Acontraetingthe rim may be applied to forms of split rims other than that shown andWhether or not such rims are providedl svithfseparate endlesstire-retaining Hanges..
